AR6 and Sea Level Rise, Part 1

by Andy May, Mar 19, 2022 in WUWT

This is the first of a three-part series on the IPCC’s discussion of sea level rise in their latest report, AR6 (IPCC, 2021). The report claims that the rate of sea level rise is accelerating. It is fair to ask why they think this, what evidence do they offer?

We find the following in the AR6 Summary for Policymakers:

“Global mean sea level increased by 0.20 [0.15 to 0.25] m between 1901 and 2018. The average rate of sea level rise was 1.3 [0.6 to 2.1] mm yr–1 between 1901 and 1971, increasing to 1.9 [0.8 to 2.9] mm yr–1 between 1971 and 2006, and further increasing to 3.7 [3.2 to 4.2] mm yr–1 between 2006 and 2018 (high confidence). Human influence was very likely the main driver of these increases since at least 1971.” [Bold added]

New Study: The CO2-Drives-Global-Warming ‘Concept’ Is ‘Obsolete And Incorrect’

by Lightfoot & Ratzer,  Mar 14, 2022 in NoTricksZone/JBasicApplSci

In analyzing UAH global temperature and Mauna Loa CO2 records from 1979 to 2021, climate researchers Lightfoot and Ratzer (2022) report there has been “little, if any” correlation between these two variables during this period.

They assert that between 91 and 98% of Earth’s greenhouse gas effect is from water vapor, as CO2 and other trace gases contribute less than 5% to greenhouse gas forcing.

A solar minimum has just began in the current solar cycle 25. The declining solar output is projected to eventually lead to a ~1 to 1.2°C cooling over the next 30 to 40 years. Solar minimum periods are also accompanied by crop failures due to frost and weather extremes delivering excessive heat.

The authors conclude by suggesting the popularized conceptualization of CO2 as a driver of global warming has proven to be “obsolete and incorrect”.

Great Reset: Germany Wants EU Ban On Petrol-And-Diesel Cars By 2035

by P. Caddle, Mar 18, 2022 in ClimateChangeDispatch

Motoring may be set to see a Great Reset in 2035, with the German government announcing they want an EU-wide ban on the sale of petrol and diesel cars.

Combustion engine cars should go the way of the dinosaur from 2035, according to the German government, who have announced they are backing a plan to ban the sale of petrol and diesel cars in the EU from that year on. [bold, links added]

Despite the country initially resisting Europe-wide legislation pushing for zero-emission cars, the Federal Republic has since about-faced on the idea of a motoring Great Reset and will join others in the bloc looking to begin phasing out hydrocarbon-burning vehicles by 2035 or earlier.

According to a report by POLITICO, the announcement that Germany will be supporting a Europe-wide banwas to be made during a meeting of EU environment ministers, according to the German Green party’s Steffi Lemke.

“The new German government stands behind the [European] Commission’s draft and thus fully supports the end of the internal combustion engine [for cars and vans] in the EU from 2035,” POLITICO reports the Green Party environment minister, Steffi Lemke, as saying.

Al Gore’s 2009 Warning on Vanishing Polar Ice and the Perils of Censoring ‘Misinformation’

by J. Miltimore, Mar 17, 2022 in FEEStories

While speaking at a climate change summit in Denmark in 2009, former Vice President Al Gore made an alarming statement.

Citing research from Dr. Wieslaw Maslowski, a professor of oceanography at the Naval Postgraduate School in California, Mr. Gore said it was likely that the north polar ice caps would soon be completely melted.

“These figures are fresh,” Mr. Gore said. “Some of the models suggest to Dr. Maslowski that there is a 75 percent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.”

New Analysis Of Greenland’s GISP2 Temperatures Expose Selection Bias In Paleo Reconstructions

by K. Richard, Mar 17, 2022 in NoTricksZone

Scientists admit that 3 different Greenland Summit (GISP2) temperature reconstruction “strategies” produce 3 different paleoclimate temperature results. The reconstructions chosen as the most “robust” are therefore the ones that align best with the authors’ presuppositions.

In a new study published in Quaternary Science Reviews scientists (Döring and Luenberger, 2022) report they reject a reconstruction of Greenland Summit temperatures that shows it has cooled ~4°C since Roman times (shown below as the red trend line, extended to 2000 C.E.).

Northern and Southern Hemisphere Warming

by A. May, Mar 18, 2022 in WUWT

…

As shown in Figure 1, the Hadley Climatic Research Unit HadCRUT5 temperature dataset suggests the Northern Hemisphere warmed 0.74°C (1.3° F) more than the Southern Hemisphere from 1979 through 2021. The UAH satellite temperature lower troposphere record is directionally similar but the difference between the hemispheres is much less, as shown in Figure 2. Both figures have identical vertical scales of 1.4°C. The UAH global satellite warming difference, from 1979 to 2021, between the hemispheres is about 0.2°C (0.4° F), less by more than a factor of 3.

…

Conclusions

The UAH and HadCRUT5 records both show the Northern Hemisphere warming more rapidly than the Southern, but the amount of extra warming in the HadCRUT5 record is anomalous. While the Southern Hemisphere satellite and surface rates are similar, the Northern Hemisphere rates are very different.

The global UAH lower troposphere and HadSST4 warming rates are both 0.14°C/decade from 1979 to 2020, the same to two decimals, as shown in my previous post. The oceans cover 70% of Earth’s surface and the HadSST4 dataset is used in combination with the CRUTEM5 land-surface temperature record to produce the curves in Figure 1. Given this, the large difference in Northern Hemisphere warming rates between Figures 1 and 2 is very hard to explain. Frankly, it suggests there is a problem with CRUTEM5. Figure 3 suggests the problem is getting worse in recent years, not better. This topic is discussed in more detail in my latest book: The Great Climate Change Debate: Karoly v Happer.

Ancient Ice Reveals Scores of Gigantic Volcanic Eruptions

by C. Rotter, Mar 15, 2022 in WUWT/ClimPast

Magnitude, frequency and climate forcing of global volcanism during the last glacial period as seen in Greenland and Antarctic ice cores (60–9 ka)

Abstract

Large volcanic eruptions occurring in the last glacial period can be detected by their accompanying sulfuric acid deposition in continuous ice cores. Here we employ continuous sulfate and sulfur records from three Greenland and three Antarctic ice cores to estimate the emission strength, the frequency and the climatic forcing of large volcanic eruptions that occurred during the second half of the last glacial period and the early Holocene, 60–9 kyr before 2000 CE (b2k). Over most of the investigated interval the ice cores are synchronized, making it possible to distinguish large eruptions with a global sulfate distribution from eruptions detectable in one hemisphere only. Due to limited data resolution and large variability in the sulfate background signal, particularly in the Greenland glacial climate, we only list Greenland sulfate depositions larger than 20 kg km−2 and Antarctic sulfate depositions larger than 10 kg km−2. With those restrictions, we identify 1113 volcanic eruptions in Greenland and 737 eruptions in Antarctica within the 51 kyr period – for which the sulfate deposition of 85 eruptions is found at both poles (bipolar eruptions). Based on the ratio of Greenland and Antarctic sulfate deposition, we estimate the latitudinal band of the bipolar eruptions and assess their approximate climatic forcing based on established methods. A total of 25 of the identified bipolar eruptions are larger than any volcanic eruption occurring in the last 2500 years, and 69 eruptions are estimated to have larger sulfur emission strengths than the Tambora, Indonesia, eruption (1815 CE). Throughout the investigated period, the frequency of volcanic eruptions is rather constant and comparable to that of recent times. During the deglacial period (16–9 ka b2k), however, there is a notable increase in the frequency of volcanic events recorded in Greenland and an obvious increase in the fraction of very large eruptions. For Antarctica, the deglacial period cannot be distinguished from other periods. This confirms the suggestion that the isostatic unloading of the Northern Hemisphere (NH) ice sheets may be related to the enhanced NH volcanic activity. Our ice-core-based volcanic sulfate records provide the atmospheric sulfate burden and estimates of climate forcing for further research on climate impact and understanding the mechanism of the Earth system.How to cite. Lin, J., Svensson, A., Hvidberg, C.

The BBC’s fake news about fracking

by P. Homewood, Mar 16, 2022 in NotaLotofPeopleKnowThat

The seasons are changing, and for many of us that means it’s time for a spring clean. My back patio has been gathering months’ worth of soil and winter debris, so I now need to blow it up. I will use the same method to clean the grime off my car. After ensuring the area is clear, and any nearby houses or pedestrians are safe, I will subject the car to lots of explosions. In each case, I shall be using a power washer, of the kind that Halfords sells for around 50 quid.

At this point, I expect the pedants among you to start quibbling. The hydraulic pressure from my power washer is not an ‘explosion’, you might point out. Water pressure does not cause ‘a sudden and rapid expansion’, which is how many dictionaries define ‘explosion’. But according to the BBC’s most senior green journalist, environment editor Roger Harrabin, there is no difference between hydraulic pressure and explosions – and Roger’s word is good enough for me.

Harrabin began to deploy the word ‘explosions’ in his reports in 2011, when the UK’s coalition government and the public began to warm to a new and emerging energy resource: shale gas.

Ancient El Niños reveal limits to future climate projections

by University of Texas at Austin, Mar 15, 2022 in ScienceDaily

The climate pattern El Niño varies over time to such a degree that scientists will have difficulty detecting signs that it is getting stronger with global warming.

That’s the conclusion of a study led by scientists at The University of Texas at Austin that analyzed 9,000 years of Earth’s history. The scientists drew on climate data contained within ancient corals and used one of the world’s most powerful supercomputers to conduct their research.

The study of the past, which was recently published in Science Advances, was motivated by the need to get a clearer picture of how climate change may affect El Niño in the future.

El Niño is the warm phase of the El Niño Southern Oscillation, a climate phenomenon that sets the stage every few years for weather patterns worldwide. Strong El Niño events, such as the ones in 1997 and 2015 that brought wildfires to the rainforests of Borneo in Asia and caused widespread bleaching to the world’s coral reefs, happened about once a decade.

Computer models, however, are unclear about whether El Niño events will become weaker or stronger as the world warms due to climate change.

Green Fuel Folly: Forest Thinning (For Wood Pellet Production) Has A Profound Surface Warming Impact

by P. Gosselin, Mar 15, 2022 in NoTricksZone

4 recent studies tell us that forest thinning for the production of wood pellets and clear cutting for wind parks are really dumb ideas. 

Reforestation and afforestation (R&A) are among the most prominent ideas for the sequestration of CO2 and thus viewed by alarmists as a climate solution. But others doubt forests play much of a role.

Wood pellets mean double barrel warming

Another solution proposed for climate protection is to burn wood pellets instead of oil and natural gas for heating buildings. Wood pellets are viewed as renewable and thus are supposed to be brakes on climate change. But now recent studies suggest that burning wood pellets coming from harvested trees in forest thinning operations may instead be accelerating warming.

HAT-TIP: Die kalte Sonne here.

Cloud–albedo effects due to land–atmosphere interactions

In their study, “Cloud cooling effects of afforestation and reforestation at midlatitudes” the team of authors led by Sara Cerasoli carefully analyzed R&A at midlatitudes. Using both satellite data and atmospheric boundary-layer models, they show that by including cloud–albedo effects due to land–atmosphere interactions, the R&A cooling at midlatitudes becomes prevalent.

This means that scientists earlier had not adequately taken the clouds that formed due to forests into account. These high albedo clouds play a major role in terms of having a cooling effect. Clouds tend to form more over intact forests than they do over forest-free areas.

Forests along with the clouds they help create, act to cool surface temperatures. Thus efforts to keep forests intact at midlatitudes would help cool the earth’s surface.

China plans massive increase in coal mining

by Bloomberg, Mar 15, 2022 in ClimateDepot

China plans a massive increase in coal mining, a move that will dramatically reduce its reliance on imports and deal a blow to its near-term climate actions.

The National Development and Reform Commission, the nation’s top economic planner, told officials from major mining regions at a meeting late last week that it wants to boost domestic production capacity by about 300 million tons, according to people familiar with the matter. It also plans to build a 620 million-ton stockpile of the fuel split between government, miners and users.

Such an increase in output would cut the country’s already scant dependence on foreign imports after global prices hit record levels in the wake of Russia’s invasion of Ukraine. The measures also highlight concerns that China’s reliance on fossil fuels remains as entrenched as ever, as it seeks to enhance energy security to limit disruptions to economic growth, regardless of the impact on its climate goals.

It’s hard to overstate the importance to China of coal, the most-polluting fossil fuel. The nation produces and consumes more than half of global supply, and it’s the biggest contributor to its world-leading greenhouse gas emissions. China has said that coal consumption should begin to fall off in the second half of this decade as it strives to peak emissions across the economy by 2030.

The production increase would be split, with 150 million tons of capacity coming from new, upgraded operations and another 150 million from open-pit mines and some mines that had previously been shut. Daily output should average 12.6 million tons, according to the NDRC, which is even higher than the record-breaking levels reached in the fall after shortages caused widespread industrial brownouts.

The NDRC didn’t give a timeline for the ramp-up, but if last year’s all-out push on production is anything to go by, it could happen relatively quickly. The added 300 million tons of capacity is equivalent to China’s typical annual imports. The nation produced over 4 billion tons of its own coal last year.

The new edicts on supply follow other measures intended to guarantee a smoothly running power system, which still relies on coal for about 60% of its needs. The government has ordered mines and power plants to sign medium and long-term contracts for 100% of their generation, and will enforce a price range of between 570 and 770 yuan a ton for those supplies.

Satellite and Surface Temperatures

by A. May, Mar 15, 2022 in WUWT

In the Great Climate Change Debate between Professor David Karoly and Professor Will Happer, Glenn Tamblyn was called upon to finish the consensus side of the debate after Karoly backed out. The details are described in my latest book. The debate contained an illuminating exchange of opinions on satellite versus surface temperature measurements. This is Glenn Tamblyn’s opinion:

“Stitching together raw data from multiple satellites is very complex. Thus, the satellite datasets are much less accurate than the surface temperature datasets.

Professor Happer’s stronger emphasis on satellite temperature measurements does not agree with the experts on the subject.”

(Tamblyn, 2021b, pp. 7-8)

Satellites measure microwave radiation emitted from oxygen atoms in the atmosphere to estimate the “brightness” temperature, which can then be converted to an actual atmospheric temperature. No correlation to any other measurements is required. The measured brightness is compared to the brightness temperature of deep space (-455°F) and a target of known temperature within the satellite to compute the actual temperature in the atmosphere.[1]

Due to interference and clouds, this technique does not work close to the surface, so satellite atmospheric temperatures cannot be directly compared to surface measurements. The satellite measurements are best for measuring air temperatures in the mid-troposphere and the lower stratosphere.

The Hadley Centre has estimated that their best current estimate of global monthly average SST accuracy(sea surface temperature average uncertainty from 2000 to 2021) is about ±0.033°C and David Karoly supplied an estimate of ±0.1°C. This is a bit less accurate than the accuracy Roy Spencer and John Christy estimate for their satellite measurements of ±0.011°C for a monthly average.[1]

“Much of the world’s temperature and rainfall are influenced by what happens in the tropical Pacific Ocean where El Niño starts,” said the study’s lead author, Allison Lawman, who began the research as a Ph.D. project at the UT Jackson School of Geosciences and is now a postdoctoral researcher at the University of Colorado Boulder. “The difference in rainfall between greater or fewer strong El Niño events is going to be a critical question for infrastructure and resource planners.”

Has Russia Been Financing Western Environmentalism?

by D. Godefridi, Mar 15, 2022 in GatestoneInstitute

  • “I have met allies who can report that Russia, as part of their sophisticated information and disinformation operations, engaged actively with so-called non-governmental organisations – environmental organisations working against shale gas – to maintain European dependence on imported Russian gas.” — NATO’s then Secretary General Anders Fogh Rasmussen, The Guardian, June 19, 2014.
  • The mechanism, which can be summarized as follows: “Funds from the Russian government -> Shell company ‘incorporated’ in Bermuda -> American foundation -> American environmental organizations.” The advantage of Bermuda is that it does not require any disclosure that funds come from a foreign government, contrary to American law. Sea Change must disclose that it has received funds from abroad — in this instance a Bermuda company. Nothing more.
  • On March 11, 2022, US Representatives Jim Banks and Bill Johnson sent a letter to Treasury Secretary Janet Yellen, asking for an investigation into the reported Russian manipulation of American “green groups” that are seemingly funded with “dark money” (anonymous donations). “Russia spent millions promoting anti-energy policies and politicians in the U.S. … Unlike the Russia hoax, Putin’s malign influence on our energy sector is real and deserves further investigation,” Banks said to Fox News Digital.
  • Below Europe’s soil lie large reserves of shale gas, also known as bedrock gas. The exploitation of these European natural gas reserves would have substantially reduced Europe’s purchases of, and dependence on, Russia’s gas — in particular on its gas giant, Gazprom. The same is true of nuclear power, which offers Westerners an abundant, non-CO2-emitting energy source as an alternative to Russian gas.
  • Hence the interest, for the Russian government, in mounting a vast disinformation campaign against shale gas and nuclear power in the West, by massively financing the groups most likely “naturally” to oppose it: environmentalist organizations.
A general view shows the headquarters of the Russian natural gas monopoly giant Gazprom building in Moscow on January 7, 2009. All deliveries of Russian gas through Ukraine were halted on January 7, intensifying a bitter dispute between Moscow and Kiev, which risks depriving Europeans of gas amid freezing weather. In a new twist, Russian Prime Minister Vladimir Putin told state-run energy giant Gazprom on January 7 to cease all deliveries of natural gas into Ukraine.

New Study: The CO2-Drives-Global-Warming ‘Concept’ Is ‘Obsolete And Incorrect’

Whither US Oil Production?

by. P. Homewood, Mar 13, 2022 in NotaLotofPeopleKnowThat

This single chart from the US EIA explains just why oil prices are shooting up there:

https://www.eia.gov/petroleum/production/

…

The oil boom initiated by Trump saw crude oil output increase by a half between 2016 and 2019.

Output naturally collapsed in early 2020 as a result of the pandemic, which affected both supply and demand. But since then output has only slowly recovered, and is still 9% below 2019 levels.

It is worth pointing out that demand in 2021 was still not back to 2019 levels. Assuming it recovers this year, it is likely to put further upward pressure on prices, unless production increases as well.

To put the numbers into perspective, the US produces a sixth of the world’s crude oil. The increase US output between 2016 and 2019 was 205 million tonnes, and represents 5% of global output.

Small changes in supply have a disproportionate effect on international oil prices, because demand is so inelastic. An extra 5% on world production would have a significant impact on prices.

Warming Could Lead To Fewer Tornadoes… Trend Has Been Downward 70 Years, Less Damage

by P. Gosselin, Mar 13, 2022 in NoTricksZone

A rational look at the data and physics tell us there are no real signs that tornadoes are going to get more frequent and worse.

German Die kalte Sonne’s 2nd part of its most recent video looks at tornadoes, a ferocious and extremely destructive meteorological phenomenon that global warming alarmists claim will only get worse and worse. They want6 you to panic over it.

But Die kalte Sonne’s video report notes that a number of sources say that trend has yet to materialize. Many statistics in fact have shown the opposite is happening:

…

 

Ideal conditions for tornado formation could weaken

The ideal conditions that lead to the formation of tornadoes are lower warm moist air clashing with cold dry air moving above. The conditions are common in the springtime, when warm, humid air from southern USA clashes with a cold air mass blasting in from the north. Yet, should the these cold masses of air warm up, then this would lead to a smaller temperature gradient and thus be less favorable for tornadoes to form.

Past global photosynthesis reacted quickly to more carbon in the air

by University of Copenhagen, Mar 10, 2022 in ScienceDaily

Ice cores allow climate researchers to look 800,000 years back in time: atmospheric carbon acts as fertilizer, increasing biological production. The mechanism removes carbon from the air and thereby dampens the acceleration in global warming.

Even under ice age conditions will plants, plankton, and other life forms be able to increase production whenever atmospheric carbon concentrations rise. The mechanism will not prevent an ongoing trend of global warming, but at least dampen the acceleration. This conclusion stems from an international collaboration involving the Physics of Ice Climate Earth (PICE) center of Niels Bohr Institute, University of Copenhagen.

“Global biosphere production through photosynthesis is the strongest absorbing flux of atmospheric carbon dioxide. It is therefore essential to understand its natural variability for a better projection of the future carbon cycle,” says Postdoc researcher Ji-Woong Yang, PICE, continuing:

“Nowadays, as we have Earth observation satellites and other advanced equipment, the mechanism of carbon fertilization is well established. However, we were not sure that the same mechanism existed in past periods where the climate was very different and atmospheric carbon concentrations much lower. The new results confirm the existence of the strong correlation and allow us to model future developments with more confidence.”

Eight glacial cycles are covered

In collaboration with Laboratoire des Science du Climat et de l’Environnement, France, the PICE team has studied the ancient air trapped inside tiny air bubbles in an Antarctic ice core. The ice core represents the last 800,000 years of climatic development.

The scientists take advantage of the fact that the oxygen atom does not only exist in the most common form 16O with 8 protons and 8 neutrons but also as the isotopes 17O and 18O. The isotopic composition is a tracer for biosphere productivity. Uniquely, the method will show the global level of biological production in contrast to other methods which give more localized results.

Combining the air bubble measurements with modeling of oxygen behavior in both the biosphere and the stratosphere, the researchers were able to quantify the biosphere productivity evolution under both glacial periods (ice ages) and interglacial periods. In total, eight glacial cycles were covered.

“The results clearly demonstrate that productivity drops during glacial periods and increases during interglacial periods. Further, a strong correlation exists with past atmospheric carbon dioxide concentrations measured from multiple ice cores. In addition, the effect is more prominent during glacial periods where the level of carbon dioxide and the global biosphere productivity start to increase several thousand years before the ice caps begin to melt. This correlation is explained by the strong fertilization effect by atmospheric carbon dioxide,” says Ji-Woong Yang.

There is no climate crisis

by R. Darwall, Mar 7, 2022 in TheSpectator

“No climate crisis” is, of course, not the spin the Intergovernmental Panel on Climate Change (IPCC) is putting on its new 3,676-page report released last month. “The choices we make in the next decade will determine our future,” the IPCC says. “Any further delay in concerted global action will miss a brief and rapidly closing window to secure a liveable future.”

It could hardly be plainer. The report is political advocacy barely masquerading as science.

The IPCC Working Group II report is not meant to be about policy; that’s the job of Working Group III, which has yet to produce its contribution to the sixth assessment report. “The focus of our new report is on solutions,” the IPCC says of the Working Group II report. “It highlights the importance of fundamental changes in society.” The solution to climate change, the IPCC claims, is renewable energy, circular economies, healthy diets, universal health coverage and social protection. The only surprise is that the IPCC didn’t include abolishing the Second Amendment in its climate catechism.

“Scientific evidence shows that addressing the risks and impacts of climate change successfully involves a more a diverse set of actors than previously thought” and involvespartnerships with “traditionally marginalized groups, including women, youth, Indigenous Peoples, local communities and ethnic minorities (high confidence).” How on earth did the IPCC exclude the LBGTQ+ community? “Different interests, values and worldviews can be reconciled if everyone works together,” the IPCC says. This isn’t science. It’s climate kumbaya.

Small islands were the poster child of net zero as they claimed they risked sinking beneath the waves thanks to rising sea levels. They successfully lobbied for the adoption of the target in the Paris climate agreement to limit the increase in global temperature to 1.5 degrees Celsius above pre-industrial levels. The IPCC therefore includes them in a list of global hotspots of high human vulnerability, asserting that their vulnerability will increase in the context of sea level rise. Yet only four years ago, the IPCC in its 1.5 degree Celsius special report stated that “observations, models and other evidence” indicate that unconstrained Pacific atolls have kept pace with sea level rises and that there had been “little reduction in size or net gain in land.”

In a blog post, Roger Pielke Jr. of the department of environmental studies at the University of Colorado Boulder notes that the IPCC lifts projections of future climate damages from studies that eliminate the choice of adapting to climate change, a practice Pielke calls “misleading at best.” Yet buried in the report is a study showing that adequate flood protection, i.e. adaptation, could avoid 95 percent of projected flood damages.

Thawing Permafrost Could Leach Microbes, Chemicals Into Environment

by C. Rotter, Mar 10, 2022 in WUWT

Scientists are turning to a combination of data collected from the air, land, and space to get a more complete picture of how climate change is affecting the planet’s frozen regions.

Trapped within Earth’s permafrost – ground that remains frozen for a minimum of two years – are untold quantities of greenhouse gases, microbes, and chemicals, including the now-banned pesticide DDT. As the planet warms, permafrost is thawing at an increasing rate, and scientists face a host of uncertainties when trying to determine the potential effects of the thaw.

A paper published earlier this year in the journal Nature Reviews Earth & Environment looked at the current state of permafrost research. Along with highlighting conclusions about permafrost thaw, the paper focuses on how researchers are seeking to address the questions surrounding it.

Infrastructure is already affected: Thawing permafrost has led to giant sinkholes, slumping telephone poles, damaged roads and runways, and toppled trees. More difficult to see is what has been trapped in permafrost’s mix of soil, ice, and dead organic matter. Research has looked at how chemicals like DDT and microbes – some of which have been frozen for thousands, if not millions, of years – could be released from thawing permafrost.

Then there is thawing permafrost’s effect on the planet’s carbon: Arctic permafrost alone holds an estimated 1,700 billion metric tons of carbon, including methane and carbon dioxide. That’s roughly 51 times the amount of carbon the world released as fossil fuel emissions in 2019. Plant matter frozen in permafrost doesn’t decay, but when permafrost thaws, microbes within the dead plant material start to break the matter down, releasing carbon into the atmosphere.

Sulfur emissions from consumption by developed and developing countries produce comparable climate impacts

by J. Lin et al., Feb 17, 2022 in Nature

Abstract

Regional consumption activities supported by domestic production and international trade have led to substantial aerosol-related emissions worldwide. Here we quantify sulfur dioxide emissions associated with consumption by developed and developing countries and assess the resulting climate impacts using an Earth system model. We find that although the consumption-associated emissions of developed countries are 40% less than those of developing countries, they lead to similar impacts on global mean surface air temperature and precipitation. This is because the effective radiative forcing induced per emission is greater for developed countries, which we attribute to the emissions being located at higher northern latitudes and being more evenly distributed zonally. Emissions from developing countries have a greater impact on temperature and precipitation over the tropical monsoon regions of China and India. Our results demonstrate the importance of trade and emission region in determining how consumption translates into global climate impact.

CO2 Emissions Hit Record High in 2021

by P. Homewood, Mar 9, 2022 in NotaLotofPeopleKnowThat

Energy-related CO2 emissions grew to
36.3 Gt in 2021, a record high

 

Global CO2 emissions from energy combustion and industrial processes1 rebounded in 2021 to reach their highest ever annual level. A 6% increase from 2020 pushed emissions to 36.3 gigatonnes (Gt), an estimate based on the IEA’s detailed region-by-region and fuel-by-fuel analysis, drawing on the latest official national data and publicly available energy, economic and weather data.

The Covid-19 pandemic had far-reaching impacts on energy demand in 2020, reducing global CO2emissions by 5.2%. However, the world has experienced an extremely rapid economic recovery since then, driven by unprecedented fiscal and monetary stimulus and a fast – although uneven – roll-out of vaccines. The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions, which led to more coal being burnt despite renewable power generation registering its largest ever annual growth. 

Emissions increased by almost 2.1 Gt from 2020 levels. This puts 2021 above 2010 as the largest ever year-on-year increase in energy-related CO2 emissions in absolute terms. The rebound in 2021 more than reversed the pandemic-induced decline in emissions of 1.9 Gt experienced in 2020. CO2 emissions in 2021 rose to around 180 megatonnes (Mt) above the pre-pandemic level of 2019.

The 6% increase in CO2 emissions in 2021 was in line with the jump in global economic output of 5.9%. This marks the strongest coupling of CO2 emissions with Gross domestic product (GDP) growth since 2010, when global emissions rebounded by 6.1% while economic output grew by 5.1% as the world emerged from the Global Financial Crisis.

Climate change can affect life on Earth. According to new research, it can also affect the dead.
A study of exceptionally preserved fossils led by a graduate student at The University of Texas at Austin has found that rising global temperatures and a rapidly changing climate 183 million years ago may have created fossilization conditions in the world’s oceans that helped preserve the soft and delicate bodies of deceased marine animals.
The fossils include squid-like vampyropods with ink sacs, ornate crustacean claws and fish with intact gills and eye tissue.
Despite being from different locations and marine environments, the fossils were all preserved in a similar manner. Geochemical analysis revealed that the conditions needed to preserve such captivating fossils could be connected to Earth’s climate.
“When I started the research, I had no idea if they would preserve the same way or a different way,” said lead author Sinjini Sinha, a graduate student at the UT Jackson School of Geosciences. “I was curious what led to the exceptional preservation.”
The research was published in Scientific Reports.

New Study Suggests The Early Holocene’s Baltic Sea Temperatures Were 5-11°C Warmer Than Present

by Weiss et al., 2022 in NoTricksZone

Baltic Sea surface temperatures may have reached 24°C 7,200 years ago compared to the current 12.7°C.

A new study (Weiss et al., 2022) indicates Baltic Sea regional surface temperatures ranged between 21-24°C from ~5.7 to 7.7 ka (thousand years ago). This period is referred to as the Baltic’s Holocene Thermal Maximum.

Temperatures dipped to 17.2°C at 1.373 ka. (The time span ranging from 0.0 ka to 3 ka is referred to in the study as the Modern Baltic, or M.B.)

The current (0.0 ka) surface temperature for the Baltic S is 12.7°C. This temperature is more than 11°C colder than the Baltic’s temperatures at 7.2 ka.
